| A fluorescence sensor based on Cd(Ⅱ) coordination polymer for recognition of nitrofurantoin | |
| 摘要: 采用溶剂热法成功合成了1个新的二维配位聚合物(CP)[Cd2(L)(dbpy)2(HCOO)(H2O)]·3H2O (1)，其中H3L=5-((4-羧基苄基)氨基)间苯二甲酸，dbpy=5，5'-二甲基-2，2'-联吡啶。CP 1经单晶X射线衍射、粉末X射线衍射、元素分析、红外光谱、热重和固体荧光光谱表征。CP 1的结构可简化为点符号为(63)的3连接二维hcb层。更重要的是，CP 1可以通过荧光猝灭效应选择性和灵敏地识别水相中的抗生素呋喃妥因，并且具有较低检测限(LOD=0.19 μmol·L-1)。此外，初步探索发现荧光猝灭机制可能是由荧光共振能量转移引起。 | |

| Abstract: A new 2D coordination polymer (CP) [Cd2(L)(dbpy)2(HCOO)(H2O)]·3H2O (1), where H3L=5-((4-carboxybenzyl)amino)isophthalic acid and dbpy=5,5'-dimethyl-2,2'-bipyridine, was successfully synthesized by solvothermal method. The structure of CP 1 was characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, IR, thermogravimetric analysis, and solid fluorescence spectroscopy. The structure of CP 1 can be simplified into a 3-connected 2D hcb layer with the point symbol of (63). More importantly, CP 1 could selectively and sensitively recognize antibiotic nitrofurantoin in an aqueous medium by fluorescence quenching effect and had a low detection limit (LOD=0.19 μmol·L-1). In addition, the fluorescence quenching mechanism may be caused by the fluorescence resonance energy transfer. | |
